Abstract: A plurality of controlling circuits control a plurality of respective shutdown switches to turn ON/OFF. A first signal system transmits, in a direction from one end of the plurality of controlling circuits to the other end of the plurality of controlling circuits, a significant signal during a normal operation and a non-significant signal when the operation needs to be stopped. The second signal system transmits, in a direction from the other end of the plurality of controlling circuits to the one end of the plurality of controlling circuits, a significant signal during the normal operation and a non-significant signal when the operation needs to be stopped. The other end of the plurality of controlling circuits transmits the non-significant signal through second signal system when a signal received through first signal system is the non-significant signal.

Abstract: An electric movable body transmits a signal including identification information identical to identification information retained in a first power storage pack via near-field communication when the first power storage pack is detached from the electric movable body. A charging device wiredly transmits the identification information received from the electric movable body to a second power storage pack. The second power storage pack transmits via near-field communication a signal including the identification information received from the charging device. The electric movable body collates whether or not the identification information included in the received signal matches the identification information retained in the first power storage pack.

Abstract: Controller of power storage pack performs communication for authentication with controller of an electric moving body according to the pattern of a current flowing through a power line in a state where power storage pack is mounted to electric moving body. Controller of power storage pack measures contact resistance between power storage pack and the electric moving body based on voltage of the power line on power storage pack side, voltage of the power line on the electric moving body side received from controller of the electric moving body, and current when communication for authentication is performed according to the pattern of a current flowing through the power line.

Abstract: A charging device wiredly transmits identification information to a power storage pack after the power storage pack is mounted. The power storage pack transmits via near-field communication a signal including the identification information received from the charging device. The charging device collates whether or not the identification information included in the received signal matches the identification information wiredly transmitted.

Abstract: Controller (12) of power storage pack (10) communicates with controller (32) of electric moving body (30) in a state where power storage pack (10) is mounted to the electric moving body. Communication wiring (Lc1) connects a node of power line (Lp1) on power source terminal (Tp) side relative to first switch (RYp) and controller (12) of power storage pack (10). Overvoltage protection circuit (19) turns off second switch (SWc) inserted into communication wiring (Lc1) upon detecting an overvoltage of power line (Lp1) during communication between controller (12) of power storage pack (10) and controller (32) of the electric moving body.
